Arecibo Observatory
SETI@home Science Arecibo Observatory has produced a new short (~18 minute)
video detailing the history of the observatory, how experiments are
conducted and ideas for the future.

The World's Largest Radio Telescope / Arecibo Observatory / Puerto Rico
The Arecibo Observatory is a radio telescope in the municipality of
Arecibo, Puerto Rico. This observatory is operated by SRI International,
USRA and UMET, under cooperative agreement with the National Science
Foundation (NSF). This observatory is also called the National Astronomy
and Ionosphere Center, although "NAIC" refers to both the observatory and
the staff that operates it. From its construction in the 1960s until 2011,
the observatory was managed by Cornell University.
The observatory's 1,000 ft (305 m) radio telescope is the world's largest
single-aperture telescope. It is used in three major areas of research:
radio astronomy, aeronomy, and radar astronomy. Scientists who want to use
the telescope submit proposals that are evaluated by an independent
scientific board.
The telescope has made appearances in motion picture and television
productions and got more recognition in 1999 when it began to collect data
for the SETI@home project. It has been listed on the American National
Register of Historic Places beginning in 2008. It was the featured listing
in the National Park Service's weekly list of October 3, 2008. The center
was named an IEEE Milestone in 2001.

Save The Last Great Telescope
The Green Bank Telescope (GBT) is the world's largest fully steerable radio
telescope and the world's largest land-based movable structure. It is part
of the National Radio Astronomy Observatory (NRAO) site at Green Bank, West
Virginia, USA. NRAO is located in the National Radio Quiet Zone, a 13,000
mile zone where all radio transmissions are either limited or banned
outright, to help the telescope function properly. With the growing
popularity of radio-array telescopes, the GBT may end up being the last
single-dish telescope of its kind built in the world. Motherboard traveled
to this remote part of West Virginia to investigate one of the last
remaining vestiges of single dish big science and the people who are
fighting for it.
On August 16, 2012, A committee appointed by the National Science
Foundation (NSF) recommended that the Green Bank Telescope be fully
divested from its inventory by 2017.

On the Road in Puerto Rico: Arecibo - Science Theater 42
The first in a new series of videos, we go "on the road" to check out
interesting science locations. First up, Arecibo observatory in Puerto
Rico. The largest single-aperture telescope in the WORLD! Since it's "on
the road", the videography isn't exactly top-notch, but it should improve
with time. Let me know what you think in the comments, and don't forget to
